Not actually a variety of grape at all, Oregon Grape root (mahonia aquifolium) is actually related to Barberry. An evergreen shrub that grows within the Northwestern regions of North America, it was well known to Northwestern tribes of Native Americans. These indigenous people would most commonly use it to treat upset stomachs.
Herbalists have taken up favor of Oregon Grape root as an alternative to Goldenseal, as it offers many of the same qualities but is much more plentiful in the wild. Studies have shown it to possess anti-inflammatory and anti-bacterial qualities, which would very well explain its ability to ease upset stomachs. Some scientists are also actively exploring the possibilities of Oregon Grape Root as an anti-cancer drug, though much more extensive testing is required before its usefulness is determined.
This is a 1 oz packet of cut Oregon Grape Root.
